TURNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 506,664, dated October17, 1893.

Application filed May 20,1893. Serial No. 474,888. (No model.)

To all whom t may concern.-

Be it known that I, QUENTIN W.-Boo'rn, of Rochester, in the county ofMonroe and State of New York,have invented certain new and usefulImprovements in Turning-Machines, of which the following is aspecification.

This invention relates to that class of turnflexible elastic turnerwhich is secured at one end to a fixed support, mechanism being providedto oscillate the turner, the elasticity of the turner permitting itslateral movement or oscillation. With this laterally-flexible andelastic turner secured at one end to a xed support, is preferably andusually employed a second turner, which may be stationary or may haveany of the movements now known in the art, that is to say, it may movelongitudinally, it may swing laterally on a pivot, it may have acombined longitudinal and lateral movement, it may have a rotarymovement continuously in the same direction, or it may have anoscillatory rotary movement, but preferably this second turner` is alsoa laterally-iiexible and elastic turner secured at one end to a fixedsupport.

The present improvements in their preferred embodiment are illustratedin the accompanying drawings, wherein- Figure l, is a front view of themachine. Fig. 2, is a vertical section thereof in a plane indicated bythe line 2-2 in Fig. 1. Fig. 3, is a vertical section of a turningmachine havingpa modified construction of operating mechanism; and Fig.4, is an edge view of the operating cam wheel shown in Fig. 3.

A, is the fixed framework, standard or support, having sidesupporting-brackets a ct with Y a central space b between them, and arear upwardly-and-forwardly-inclining bracket c forked at its lower endso as to form a slot d, all preferably cast of iron in a single piece.

B, B are the two laterally-liexible, elastic, and laterally-movableturners, which are s'ecured at their lower ends to the fixed supportingbrackets a a respectively. Each turner is preferably composed of twomembers, a rigid upper working member e, and a spring shank or member f,both of metal. Each working member e, has a flat, thin working end orblade, and becomes thicker at its lower end where it is screwed,riveted, or otherwise secured to the upper free end of the springshank-memberf. The spring shank or member fconsists of a flat strip ofmetal, preferably steel, which is screwed, riveted, or otherwise securedto the inner face of one of the fixed brackets a. The presence of thisspring shank renders the turner as a whole laterally ieXible.

The two turners B, B', are arranged opposite to each other, andpreferably with their flat working ends or blades overlapping each otherand lying face to face in close proximity. To prevent any sidewise'motion of the turners, the rear bracket o is extended upwardly so as toform a guide or guide-plate on one side, and a guide-plate C secured atits ends to the bracket c affords the guide or guide-plate on theopposite side. Below tlie guide-plates, the turners are separated, asshown, with a space between them.

To operate the turners, a rotating main shaft D is employed, which isjournaled in the lower end of the rear bracket c, and has a drive-pulleyg. The shaft is rotated rapidly, say twelve hundred rotations a minute.E, is arock-shaft journaled in the brackets a a, below the turners. Thisrock-shaft has an upwardly-extending crank-arm h located in the space hand between the turners, which at its upper end hasacam-block F withoppositely-inclined cam-faces i i on its opposite sides with which theturners respectively co-operate. The spring shanks f f are usuallysufficient to maintain the turners in proper co-operative relation withthe camfaces c' t', but if not they are supplemented by a spring G,connected at opposite ends to the two turners respectively. Thecrank-armh of the rock-shaft is connected by a connecting-rod or link Hwith an eccentric I (or its equivalent, a crank) located within the slotd, and carried by the main shaft D. Hence as IOO the main shaft isrotated the cam-block F is oscillated back and forth, and the turnersare moved laterally in opposite directions. The working hat end of eachturner moves edgewise, or in its own plane.

Various modifications are feasible without departing from the principlesof the invention. For example, as shown in Figs. 3, and 4, the rockshaft and link H, are omitted, and the main shaft occupies the positionof the rock shaft. Instead of the crank-arm h and cam-block F, the mainshaft carries a wheel F', provided at its rim on opposite sides with camfaces co-operating with the two turners. As shown, the wheel F', has aplurality of cam-faces w on each side, so that the desired number oflateral motions of the turners in a unitof timeare effected with acorrespondingly sm aller number of rotations of the main shaft In Fig.3, only the working end of the turner B', is shown, and the spring G isnot shown, in order to indicate that the resilience of the springshanksf may alone suffice.

I claim as my inventionl. A laterally-flexible andlaterally-movableturner having an elastic shank, said turner being secured at one end toa fixed support, in combination with means for moving said turnerlaterally, substantially as set forth.

2. Two laterally-flexible and oppositely and laterally movable turnerswhich overlap each other at their free Working ends, each having anelastic shank and each being secured at one end to a fixed support, incombination with means for moving sald turners laterally in oppositedirections, substantially as set,

4. A laterally-flexible and laterally-moving turner secured at one endto a xed support, in combination with a rock-shaft having a crank-armwith a cam thereon co-operating with said turner, a rotating shaft withan eccentric, and a link connecting said eccentric with said crank-arm,substantially as set forth.

5. A support having two separated brackets with a space between them,two laterallyflexible and oppositely and laterally moving turners fixedat their lower ends to said brackets respectively, said turners beingseparated at their lower ends, in combination With a rock-shaftjournaled in said brackets, a crankarm on said rock-shaft located in thespace between said brackets, a cam-block on said crank-arm locatedbetween said turners, said cam-block having cam-faces on its oppositesides with which said turners respectively cooperate, a springmaintaining said turners in operative contact with said cam-block, arotary main shaft having an eccentric, and a link connecting saideccentric and said crankarm, substantially as set forth.

6. A laterally-flexible and laterally-moving turner composed of twomembers connected together, a rigid working member, and a spring memberwhich is secured to a fixed support, substantially as set forth.

'7. The two laterallymoving turners, in combination with the bracket cand plate C constituting guides for said turners, substantially as setforth.

In Witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

QUENTIN W. BOOTH.
